Which is a characteristic of colloids?
a. are homogenous mixtures
b. have large dispersed particles
c. will settle out over time
d. are made up of at least two substances
Answer:
D
-----------------------------------------------------------------
The definition of colloids is very disputed on whether or not it is homo/heterogenous. I wouldn't go with this answer, but its based on what you learned it was. At a microscopic level its hetero but at a macroscopic its homo.
They do have somewhat large dispersed particles but this better describes suspensions
They don't easily settle out.
And in order to be a mixture, they are made up of at least two substances
D is likely the best answer out of the bunch.
Colloids are made up of at least two substances. Therefore, option d is correct.
What are colloids?A colloid can be described as a mixture in which one substance consisting of dispersed insoluble particles is throughout another substance. The particles should be dispersed in a liquid. The term colloidal suspension can be referred to unambiguously as the overall mixture.
A colloid exhibits a dispersed phase and a continuous phase. The dispersed phase particles have a diameter of about 1 nm to 1 μm. Some colloids are translucent due to the Tyndall effect and other colloids can be opaque or have a slight color.
Hydrocolloids can be described as certain chemicals that are colloidally dispersible in water. Therefore becoming very "soluble" they can change the rheology by raising the viscosity.
A colloid possesses a dispersed phase and a continuous phase. A solute in a solution is individual molecules, whereas colloidal particles can be bigger.

The Rocky Mountains run parallel to the western coast of the United States. While parts of the California coast are lush and tropical, the area just east of the mountain range is a dry desert. What BEST explains the drastic climate difference between these two adjacent areas?
Answer:
The mountains cause rainfall.
Explanation:
The fact that the mountains run parallel to the coast is the key in the difference in climate between the two areas. Since they are parallel to the sea, they block the wind and moisture coming from the sea towards the land, the mountains cause this air to rise and when it hits the cold air at higher altitudes, it results in rain. This leads to the lush and tropical areas whereas without the parallel mountains to the coast, the amount of rain the area receives decreases, resulting in a desert like environment.

An aluminum ion has a charge of +3.
A fluorine ion has a charge of -1.
An oxygen ion has a charge of -2.
Below, the correct charges of the elements are listed;
A lithium ion has a charge of +1 A calcium ion has a charge of +2 An aluminum ion has a charge of +3 A fluorine ion has a charge of -1 An oxygen ion has a charge of -2The ionic or electrical charge of an element is the new state the element acquires because of losing or gaining an electron.
When elements lose their electrons, they tend to attain a positive charge and when they gain an electron, they tend to acquire a negative charge. To easily identify the charge of the ions, the periodic table should be used.
Elements (metals) found on the left side of the periodic table tend to have a positive charge while elements (non-metals) on the right side of the table usually assume a negative charge.

A rectangular solid has a length of 3 cm a height of 4 cm and a width of 5 cm what is the solid volume ?
Using the enlarged metric ruler segment shown below, what is the length of the
blue line in centimeters?
Answer:
1.8 cm
Explanation:
To measure length, use a metric ruler. It is separated into centimeter-sized units. One centimeter is represented by each number on the ruler. The longest mark is the centimeter.
What is the enlarged metric ruler segment?A metric scale is used to quantify traits or variables. Interval scales, ratio scales, and absolute scales are all grouped under the phrase “metric scale.”
The majority of statistical calculations and comparisons are possible with quantitative numerical values.
To the nearest tenth of a centimeter (0.1 cm), a metric ruler, for instance, may measure length. Using a separate metric ruler, you can measure lengths to the nearest 0.05 centimeters (0.05 cm).
The measurement with the lowest degree of uncertainty (0.05 cm) is more accurate.
Therefore, 1.8 cm is the length of the blue line in centimeters.

freezing
solidification
Answer:
Explanation:
boiling
According to the forces of attraction, boiling takes place when the kinetic energy of molecules overcomes the intermolecular forces.
What are forces of attraction?Forces of attraction is a force by which atoms in a molecule combine. it is basically an attractive force in nature. It can act between an ion and an atom as well.It varies for different states of matter that is solids, liquids and gases.
The forces of attraction are maximum in solids as the molecules present in solid are tightly held while it is minimum in gases as the molecules are far apart . The forces of attraction in liquids is intermediate of solids and gases.
The physical properties such as melting point, boiling point, density are all dependent on forces of attraction which exists in the substances.

Answer:
The answer is 2.70 g/mLExplanation:
The density of a substance can be found by using the formula
[tex]density = \frac{mass}{volume} \\[/tex]
From the question
mass = 4.86 g
volume = final volume of water - initial volume of water
volume = 17.3 - 15.5 = 1.8 mL
So we have
[tex]density = \frac{4.86}{1.80} \\ [/tex]
We have the final answer as

Fish are obviously animals because they move, they have sensory organs (eyes, mouth, barbels), and they have body structure (skeletons, skin, etc.). They breathe oxygen. They eat other organisms to survive. Fish are different from other animals because they live in water.
Answer:
The surface fish live near the surface of the water, and the blind cave fish live in dark subterranean caves. The surface fish have eyes and pigmentation on their bodies. The blind cave fish don’t have eyes, and they’re often albinos.

C. at an acute angle measuring 23 degrees
Answer:
1 closer
2 24hours
3 tidal bulges
4 in a straight line
Explanation:
Tides have been the effect of the sea with the gravitational pull of the sun and moon.
1. Earth’s tides are affected by the gravitational pull of the Sun and the Moon, but mainly the Moon because the Moon is closer to the earth.
In spite of high pull of the Sun, the distance of moon from earth results in increased effect of moon gravitational pull than Sun.
2. Each day, each coastal region on Earth experiences two high tides and two low tides in every 24 hours time period.
The daily tides has been resulted at the coast with the moon revolution around the earth's rotation.
3. This is because the gravitational attraction of the Moon creates tidal bulges on two opposite sides of the planet.
The effect of the moon gravitational force results in the bulging or the pulling force to the sea, resulting in the diurnal tides.
4. Two spring tides occur monthly, when the Moon is in its new and full phases. During these phases, the Moon and Sun are oriented at a right angle measuring 90 degrees which gravitation pulls the water on Earth in the same direction, creating a large tidal range.
